Eungsop Yoo updated HDFS-16198: ------------------------------- Attachment: (was: screenshot-1.png) > Short circuit read leaks Slot objects when InvalidToken exception is thrown > --------------------------------------------------------------------------- > > Key: HDFS-16198 > URL: https://issues.apache.org/jira/browse/HDFS-16198 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Eungsop Yoo > Priority: Major > Attachments: screenshot-2.png > > > In secure mode, 'dfs.block.access.token.enable' should be set 'true'. With > this configuration SecretManager.InvalidToken exception may be thrown if the > access token expires when we do short circuit reads. It doesn't matter > because the failed reads will be retried. But it causes the leakage of > ShortCircuitShm.Slot objects. We found this problem in our secure HBase > clusters. > !screenshot-2.png! > The fix is trivial. Just free the slot when InvalidToken exception is thrown. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
